Ban me if you dare, but i bet you will use it as well
how to use:
just click HELP button for each phone type
to find out IMEI for Nokias, unlock keyboard and write down *#06#
after typing IMEI, you will get one number (i got 4), take a look at calculate, and choose code with same number
If your mobile doesnt unlocks for other coutry/provider use, use seventh calculation.
warning: after 7 wrong tries, only your provider or special cable will help.
examle: after typing IMEI, you get number 6, choose serial number with +6 extension.
any questions welcome
Enjoy
